Locksley Resources (ASX:LKY) advances Greater Tottenham technical programme
Locksley Resources has established an operating base at Tottenham and commenced metallurgical sampling as its technical programme advances across the Greater Tottenham copper and gold district in central New South Wales, following the strategy outlined to the market on 15 October 2026.
Highlights
Historical diamond core is being reviewed to support geological modelling, exploration targeting and resource work.
Iron Duke drilling approvals are well advanced, with a drill rig contract being finalised.
Drill planning is progressing at Carolina and Mount Royal/Orange Plains.
An independent Mineral Resource Estimate and JORC Exploration Targets are being finalised.
Greater Tottenham sits within the Girilambone Basin of the Lachlan Fold Belt, where Locksley has an existing resource foundation, multiple brownfield growth centres and an extensive historical dataset.
Its programme is designed to turn that information into a ranked pipeline of drill targets and begin drilling the highest priority targets as approvals and access allow.
The local operating base will support core processing, sampling, storage and field logistics for historical core review and future drilling.
A generator, all terrain forklift and core saw are operational, while site preparation continues and a marquee is planned to provide additional covered core handling space.
Locksley’s geologists are reviewing historical diamond core from more than 70 holes drilled over several decades, with reference to previous logging.
The core review programme covers selected intervals from approximately 8,700 m of core from 38 holes stored at Tottenham, beginning with Carolina and Mount Royal/Orange Plains.
This work is establishing a unified geological model and feeding a consolidated historical database, while identifying intervals not sampled by earlier explorers for assaying.
Selected core intervals are also being cut to provide samples for metallurgical testwork.
At Carolina, samples have been collected from 2 historical diamond holes approximately 100 m apart, where sufficient fresh sulphide material is available.
Available material at Mount Royal includes only limited oxide and fresh intervals, and historical records and other potential sample sources are being reviewed to complete a representative sample set covering oxide, transitional and fresh mineralisation.
This work will define the scope of the planned testwork programme, with no metallurgical results reported in the announcement.
Historical electromagnetic and induced polarisation datasets are being integrated with geological and drilling information, including additional historical induced polarisation data previously held only in hard copy.
Geological and geophysical consultants are finalising 3D geological and GIS models within a target ranking framework that will determine drilling order.
Locksley Chairman Bevan Tarratt said,
“Each of these workstreams has the same goal: getting a drill rig onto the best targets in the district.”
At Iron Duke, the initial design for permitting comprises approximately 5,500 m and includes 28 pads, allowing flexibility in selecting initial and follow up holes.
It targets a gap of 100 m to 150 m in the southern part of the known mineralisation, together with infill and extensions down dip to the north.
A closer spaced programme of approximately 10,000 m is being planned to test sparsely drilled southern parts of Orange Plains/Mount Royal, while Carolina drilling will target higher grade mineralisation remaining open along strike and down dip.
A rig is expected to be available later in the calendar year, at the same time permitting is expected to be approved by the NSW Mines Department.
Landholder access arrangements are progressing, while the independent resource estimate and Exploration Targets will be reported once finalised and reviewed by the Competent Person.
